corydalis sheareri/抗癌藥

BACKGROUND Cancer is one of the leading cause of unnatural death globally. There is still a great need for effective anticancer agents from plant sources. Corydalis saxicola Bunting is a medicinal plant that is traditionally used to treat various diseases in southwest China. Previous phytochemical

OBJECTIVE To investigate the chemical constituents of Corydalis ochotensis and their antitumor bioactivity. METHODS The compounds were isolated by silica gel column chromatography and recrystallization. Their structures were identified by spectroscopic analysis (NMR) and physicochemical properties.

Synergy analysis of anticancer agents is an important approach to determining the ratio and/or dose of drugs for clinical combination therapy. However, this method is rarely used to evaluate the composition of traditional Chinese medicine formulation. 'Yanhusuo San' (YHSS), which consists of

Corydalis saxicola Bunting (Yanhuanglian) is an important component in various prescriptions in traditional Chinese medicine. Yanhuanglian has been demonstrated to possess many pharmacological activities, including antibacterial, antiviral and anticancer activities. The active fractions are

Alkaloids have protective functions for plants and can play an important role in living organisms. Alkaloids may have a wide range of pharmacological activities. Many of them have cytotoxic activity. Nowadays, cancer has become a serious public health problem. Searching for effective drugs with

Corydalis saxicola Bunting (Papaveraceae), a traditional folk medicine, has been used to treat hepatic diseases for a long time. Owing to its signicant clinical effectiveness against hepatitis, cirrhosis and hepatoma, C. saxicola and its preparation are widely applied. In this study, eight

Cell division cycle 42 (Cdc42) is a critical regulator, which functions in cancer metastasis. Numerous previous studies have demonstrated that vav guanine nucleotide exchange factor 1 (Vav1) is ectopically expressed in numerous types of human malignancies and have suggested that Vav1 may efficiently

BACKGROUND Corydalis cava Schweigg. & Koerte, the plant of numerous pharmacological activities, together with the studied earlier by our group Chelidonium majus L. (Greater Celandine), belong to the family Papaveraceae. The plant grows in Central and South Europe and produces the sizeable

Though Dehydrocorydaline, an alkaloid isolated from Corydalis turtschaninovii tuber, was known to have anti-coronary artery disease, anti-inflammatory, apoptotic, anti-allergic, anti-acetylcholinesterase, and antitumor effects, the underlying anti-metastatic mechanism of Dehydrocorydalin was never

Natural product corynoline is a unique isoquinoline alkaloid extracted from traditional Chinese medicine Corydalis bungeana Turcz, whereas its anticancer properties have not been investigated. In this study, we found that corynoline potently impairs the growth of melanoma cells, B16F10, and A375 in

Chemical studies of the Chinese herb Corydalis saxicola Bunting led to the isolation and identification of 14 alkaloids, 1-14. Seven of these compounds, 4-9 and 11, were obtained from this plant for the first time. Feruloylagmatine (7) is the first guanidine-type alkaloid to be identified in the

Cancer is one of the most occurring diseases in developed and developing countries. Plant-based compounds are still researched for their anticancer activity and for their quantity in plants. Therefore, the modern chromatographic methods are applied to quantify them in plants, for example, UPLC-MS/MS

OBJECTIVE Our previous works have demonstrated that Chinese herb medicine yanhusuo (Corydalis yanhusuo W. T. Wang) has strong anti-cancer proliferation effect in MDA-MB-231 cells. The goal of this study was to find out the synergic cytotoxicity effect of three natural compounds, tetrahydropalmatine

Overexpression of P-glycoprotein (P-gp) and multidrug resistance-associate protein 1 (MRP1) is a major mechanism leading to multidrug resistance (MDR) of cancer cells. These transporters expel anti-cancer drugs and greatly impair therapeutic efficacy of chemotherapy. A Chinese herbal plant Yanhusuo

Corydalis yanhusuo, a well-known traditional Chinese medicine, is widely used in China as an analgesic for patients with terminal cancer. In this study, we want to expose the antiangiogenic effects and the underlying mechanisms of C. yanhusuo and the alkaloids obtained from this plant. The
